Isegrim: Just download the game by clicking the disk icon at the upper middle of the screen ("Particles.swf (2.3MB) Save"), then extract the .mp3 from the .swf with any tool you find googling for "swf2mp3" or ".swf to .mp3". (July 3, 2007, 5:59 pm)

oh lawd: The music is made by Dimrain47 and the track is called Twilight Techno and can be downloaded from Newgrounds' audio portal. Just search for Dimrain47 or Twilight Techno and then find the download button. (August 19, 2008, 9:52 pm)

Anaali: "Then one day you realize that you can see the spaces between the bullets instead of the bullets themselves. You feel like Neo as he saw the truth behind the Matrix. You complete HARD MODO." (December 23, 2011, 11:57 pm)
